Torsional Fatigue

This paper is aimed to investigate the effect of roller working on the torsional fatigue properties of a typical low carbon steel referring by the resutls of FEM analysis. Three types of specimens had been prepared with plastic deformation value of 0, 0.5 and 1.0mm, respectively. The main results obtained in this study are as follows: (1) The torsional fatigue strength of roller-worked specimen with 1.0mm plastic deformation is increased more than twice of that of non-rollerworked specimens. (2) Surface hardness of roller worked specimen is much higher than that of the non-roller worked one, and compressed and elongated structure is formed at the notch bottom of the specimen. (3) Crack length along the axial direction of roller worked specimens is longer than that of the non-roller worked specimen, and plural cracks initiated and propagated in the roller worked specimens. (4) The residual stress distribution at the specimen’s notch bottom was analysed using FEM analysis and it is verified the same tendency as the experimental results.

through super-hard wear-resistant surface electrode surfacing D707 in Low-carbon steel. We have analysis the effect of welding process parameters and post-weld heat treatment process on low carbon steel surface hardness of cladding layer. The experimental results show that: after quenching hardness value no significant change; But after annealing the hardness value decreased and after annealing the crystal grain of the underlying tissues uniformization become tiny. micro-hardness testing is carried out in the weld cross-section, we have find out that from the base metal to the cladding layer the surface hardness values is getting higher and higher, while the indentation is getting smaller and smaller. Because hardness is a measure of wear resistance materials, thus it can indirectly show that when low-carbon steel surface electrode in the super-hard wear-resistant surfacing welding layer, it can improve the surface hardness of low carbon steel and improve wear resistance of low carbon steel surface.
